,IMPRQyl-:MENT IN BooK-BINDIGS- Specification forming'fpart of Letters'Patent No.; 176,286, dated April 18, 1876;

application filed January 24, 1876.

Whichiare provided-with aseparable or false cover, from -which the book properean be 'readily'detacl'ied whenever desired;` and the iirst part "of` ourimprovements comprises a novel co1istrl'l'ctionof-'sockets-for said separa! ble cover. These Psockets are adapted to receive the apsQr" backs ofthe' book prper, as.

hereinafter more fully jexplainedp"l 1 The secondrgart of our improvements consists inineasing the-ed, ges ot the "covers,` the.

hubs 7 ofthe back, andoth-ei prominentparts ot' `the book` With-Yinetallie -bindings,"thereby Aaddin g1 tofthe durabilityandfappearanceof the covers. y J I 1.

The thirdpart of ourjinproveinen tslc'onsists in provid-ing thetop AandbottoniE'ol" fthe backbindingY with metallic tips, that prevent the back `being injurednwhen thelbook ,is Withdrawn from ashelf or. other support.

In the annexed drawings, Figurel is a per,- spective viewgot"abook provided with `our improved bindings," the book Abeingshown detached from its` separable cover. Fig. 2 is a horizontal.sectiomshowing thfe flaps of the book proper. 'engaged with' theappropriate `sockets of theseparable cover. Fig. 3 is a perspectlve vlew ot' aportion of theback land covers of the vseparable member of thebook. l Fig. 4 is-a horizontal Vsection through a.portion of one ot' the sockets.` Fig. 5 is ahorizontal section through one offthe metallic tips; and Fig. 6 isa `perspective View of one ofthe separable covers` andit-s sockets, previous to being united to the back.

Of the aboveillustrations, Figs. 3, 4, and 5 are drawn on lanenlarged scale. A

A' represents ledger or ijournal, or other blank-bool ,and B `B', are the covers or flaps of thesanie. As these flapsv arenot exposed when the 'bookv is in use, theymay be made quiteplainpand need `not be Very thick or heavy` O C' yrepresent two stout covers of ,any suitable material, saidcovers bein g united to the backhylhe customary flexible joints c c'. Firmly attached to the top', bottom, and outer margins ot these covers are tillings E, composed ot' one or more narrow strips of pasteboard., leather, wood, or other light material. Secured to the llingsE of cover C is a sheet of pasteboard, F, ot' the saine size as said cover, but of somewhat thinner material.

F' represents a preeisvly similar sheet secured to the other cover, C'. By -this arrangement of' covers, llings, and sheets, two sockets or receptacles, G G', are formed ot' such capacity -a's to readily receive the appropriate aps B B' of the blank-book A. These sheets F F are provided, respectively, with slots f f', which slots allow said' sheets to spring or bend away from the covers C C' when the lia-ps B B' are inserted in the sockets Gr G'.' Y The back D is ist'ii'enedwith any suitable number of hubs, "H1, that are ineased i-n sheet-metal:mountings I, which latter -may be secured in position with prongs or rivets J J', asseen'in Fig. 5. Attachedto the'upper part` of" back D is a metallic tip, K, having a' tlange,f7c, that projects over the extreme end of said back. The

' lower end of the back is shodwith aprecisely similar anged tip, L l. These tips may be secured in position with rivetsor` tongues J J', as shown in Fig. 5. Furthermore, the ends ot'these tips, together with the` ends of hubmountings l, may be soldered to sheet-metal libs M M', disposed longitudinally of back D. These ribs are preferably'loeated at or near the junctions of the joints c c with, said bgck. 1n order to sti'en, and at the'same time proteot, the covers C C', the edges of `the latter are incased `within sheet-metal mountings N, ot' any appropriate material. These. mountings are forced upon the covers, so as to 'cause the edges of the sheet metal to embed themselves in the substance of the covers, as more clearly shown in Fig. 4; or, it' preferred, suitable grooves or creases P may be made in the backs C C' and inner sheets F F', so as to afford a more secure hold of the mountings. These grooves are seen in Fig. 6. rllhe bindings N are mitered at their junctions and then soldered together, the joints being rounded o', so as to avoid sharp angles. The inner ends of said bindings or mountings, which are fastened to the tops and bottoms of the covers C U', are united together with ribsO O', that i NITED PATENT FFICE are located at the junctionof said covers with the joints c c.

The book A, which may he a ledger or any other account or blank book, is applied to the separable or false cover in the following manner: Said book and cover are first opened, as shown in Fig. l. and the flaps B B are inserted Vin the mouths of the sockets G Gr', after which the book A is drawn toward the separable member C C D. lhis act causes the flaps B B to completely traverse the sockets or receptacles, and as soon as the back of book A comes in contact with the back D, the bookV A B B is at once secured In its proper position. While the flaps B B' are being' inserted in their appropriate sockets G G', the slots f f' allow the inner sheets F F to spring far enough to permit said tlaps sliding in with the utmost ease, and without subjecting either the book A or the separable cover to any injurious strains. These slots allow the sheets F E of the sockets to give far enough to compensate for any warping or springing ot' the inps B l'. The blank-book, having been thus applied to the separable cover, may be opened and closed with even greater facility thana book of the saine size cnn be when bound in the usual manner. When the ledger has been lillcd, the covers C C are bent back to the position shown in Fig. 1, the aps B B' are `withdrawn from the sockets Gr G', and a new account-book is at once substituted for the old one. By this means the heavy and comparatively expensive separable cover may be rendered useful for protecting an indefinite number of books of any kind.

The tip K k is another important feature of our improvements, as it prevents the back D being sprung and torn when the book is with drawn from a shelf, the upper 'end of said back being the part that is always grasped for such a purpose. The lower tip L l coacts with the monntings N on the bottom edge ot' covers C C', to prevent injury to the covers when the book is shoved in upon a shelf, or withdrawn therefrom. For small blank-books the slots f j may be omitted. The tips on the ends ofthe hack D may be composed ot' bone, hard rubber, or other material.

We are aware that it is not new to provide books with separable backs or covers, such covers being seen in Letters Patent No. 84,564, issued December 1, 1868, to L. G. Matthews, and, therefore, we do not propose to claim, broadly, the separable backs, "but only our special devices for increasing the capacity ot these pockets, so as to contain large and heavy books.

We claim as our invention-- 1. The sockets Gr G,formed by the covers C C', fillings E, and inner sheets F F of a false or separable book-cover, for the purpose specilied.

2. The combination of the separable cover U C D, fillings E, and inner slot-ted sheets F f F'f', as and for the object stated.

3. The metallic binding N, havin g its edges seated in the grooves on creaseslJ of the cover C, as and' for the purpose explained.

In testimony oi' which invention we hereunto set our hands.
